Abstract: A roof for a cab of a machine includes a roof surface with a rearward incline having a front portion higher than a rear portion. The roof surface has a recessed portion at the rear portion that receives a Heating Ventilation and Cooling (HVAC) unit. The recessed portion includes a rearward facing sidewall with a rearward incline, such that an upper end of the rearward facing sidewall is closer to the front portion than a lower end. The rearward facing sidewall has a lateral opening, a pair of lateral sidewalls, and a base with a rearward incline, such that a front end of the base is higher than a rear end. The base has an upright opening with a ridge protruding upward, defining a perimeter of the upright opening. The rearward facing sidewall, the pair of lateral sidewalls, and the base, define a contiguous peripheral portion of the recessed portion.

Abstract: A cabin is disclosed for use with a mobile machine. The cabin may have a floor and a roof. The cabin may also have at least one A-post located at a leading end relative to a forward travel direction of the mobile machine, and a C-post located at a trailing end opposite the at least one A-post. The C-post may have two terminal ends located at the floor, and a single terminal end located at the roof.

Abstract: Hydrocarbon solvent solutions of alkylaluminoxane are made by mixing trimethylaluminum and a hydrocarbylaluminum compound, which compound contains at least one hydrocarbyl group having 2 or more carbon atoms, in a hydrocarbon solvent and thereafter adding water or a hydrated compound so as to form a solution of alkylaluminoxane in said solvent.
